[Solved] SystemD user fails after recent updates

vendion · 2017-06-13 00:07:28

After a recent update, I noticed this a few days ago so maybe on Friday, something changed that now causes my SystemD user session to fail. At the system level everything seems fine systemctl status doesn't report that there are any failed services

systemctl status
● Vili
    State: running
     Jobs: 0 queued
   Failed: 0 units
    Since: Mon 2017-06-12 19:13:06 EDT; 35min ago

but if I run systemctl --user status I get the following error

systemctl --user status
Failed to connect to bus: No such file or directory

Dbus is currently running so that probably isn't the "bus" that systemd --user fails to connect to

> systemctl status dbus.service

Looking at the dmesg logs I do see the following error that occurred when I logged in

I'm not sure what to make of the "No such file or directory" as /usr/lib/systemd/systemd is a file on my system and has both read and executable bits

> file /usr/lib/systemd/systemd
/usr/lib/systemd/systemd: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=8d3cb750275dc2f474dc7f049fdffb3a649b1d49, stripped
> ls -l /usr/lib/systemd/systemd
-rwxr-xr-x 1 root root 1104576 Jan 28 17:32 /usr/lib/systemd/systemd*

I don't use a login manager, instead I just login via tty1 and then run startx to start up X11 and run my window manager, in case this matters. I'm kind of stumped on what else to check to try and fix this, I don't see anything posted on the "Latest News" section of the homepage about any breakage/manual changes required, at the same time I didn't make any configuration changes that I remember so I'm not 100% certain it was a package update that broke things.

Anyone here have any ideas?

What's in your xinitrc?

So I think I figured it out, it seems gpg-agent.service causing problems as after deleting $HOME/.config/systemd/user/default.target.wants/gpg-agent.service and logged out and back in and everything seems to be working now and running systemctl --user status works as expected.

Not exactly sure how and why gpg-agent.service was breaking my user session but it seems to be the culprit.

Edit: I guess my fault for not checking the Wiki first as the section on starting gpg-agent via SystemD User has changed since I last checked it.
